Title: multiple gpu issue with pyopencl
Post by: reyals on November 13, 2012, 03:25:25 AM
Since this issue extends to poclbm/guiminer.py  I thought maybe you guys might have some experience...
ATI correctly notes 2 cards

Quote
aticonfig --list-adapters
* 0. 01:00.0 AMD Radeon HD 6900 Series
  1. 02:00.0 AMD Radeon HD 6900 Series

* - Default adapter
However pyopencl only sees one
Quote
python pyopencl/examples/demo.py
Choose device(s):
  • <pyopencl.Device 'Cayman' on 'AMD Accelerated Parallel Processing' at 0x12511f0>
    • [1] <pyopencl.Device 'Intel(R) Core(TM)2 Quad  CPU   Q9550  @ 2.83GHz' on 'AMD Accelerated Parallel Processing' at 0x174eda0>
and so poclbm only sees the same
Quote
python poclbm/poclbm.py
No device specified or device not found, use -d to specify one of the following

  •    Cayman
    • [1]   Intel(R) Core(TM)2 Quad  CPU   Q9550  @ 2.83GHz
The card is good and it's driving a second monitor
I've tried both the stable and beta releases of ATI drivers... (even tried an older release but that just seemed to break more things then it fixed)
Thoughts?

Will tip if someone can solve...


Edit: To note.  I have tried several other threads with similar problems to no avail.
